technical field

The invention relates to a device for automatically, quantitatively and accurately adding diluent to ink cartridges used in the printing industry.

Background technique

At present, in the printing industry, due to the volatilization of the diluent, it is necessary to add a diluent to the printing ink from time to time during the production process to ensure that the viscosity of the ink is appropriate.

At present, the commonly used methods of adding diluents are one is to add manually based on experience, and the other is to add in the form of a dropper, and these two methods have a common disadvantage: that is, the amount added each time cannot be precisely controlled.

The technical problem to be solved by the present invention is to overcome the defect that the addition of diluent in the printing industry cannot be automatic and accurate, and provide an automatic quantitative and accurate diluent adding device.

In order to solve the above-mentioned technical problems, the present invention proposes the following technical solutions: a diluent automatic quantitative and precise adding device, including a container barrel, a lower cover plate, an upper cover plate, a ball valve for feeding pipeline, a funnel, and an air inlet pipe joint , an air inlet pipe, an exhaust pipe ball valve, an electromagnetic valve, a liquid catheter, and a liquid outlet pipe;

The lower cover and the upper cover are installed on the bottom and top of the container barrel respectively, and the lower cover, container barrel and upper cover are installed and fixed to form a closed container;

The feeding pipeline ball valve is installed on the upper cover plate;

The funnel is installed on the upper part of the feed pipe ball valve;

The inlet pipe joint is installed on the upper cover;

One end of the intake pipe is connected to the intake pipe joint, and a pipeline throttling valve is installed on the intake pipe;

The exhaust pipe ball valve is installed on the upper cover;

The solenoid valve is installed on the upper cover plate;

One end of the catheter tube is connected to the electromagnetic valve, and the other end extends into the container barrel;

One end of the liquid outlet pipe is connected with the solenoid valve.

The further limitation of the above technical solution is that the diluent automatic quantitative and precise addition device also includes two observation pipe joints and a liquid level observation pipe, the two observation pipe joints are installed on the upper and lower parts of the side wall of the container bucket, the liquid level The level observation tube is installed between the two observation tube joints, and the liquid level observation tube is a transparent tube.

The further limitation of the above technical solution is that the diluent automatic quantitative and accurate adding device includes four pull rods, and the four pull rods are installed at the four corners of the lower cover and the upper cover, and the lower cover, the container barrel, the upper The cover plate is installed and fixed to form a closed container.

A further limitation of the above technical solution is that the other end of the air intake pipe is connected to a constant pressure air source pipeline, so that the container barrel maintains a constant air pressure.

Compared with the prior art, the present invention has the following beneficial effects: through the cooperative use of the air intake pipe, the air intake pipe joint, and the ball valve of the exhaust pipe, a constant pressure can be maintained in the container barrel, thereby ensuring that the air flow through the electromagnetic valve can be guaranteed within a certain period of time. The diluent flow rate is constant, so the opening and closing time and the opening and closing time interval of the solenoid valve can be controlled according to different needs, so as to achieve the purpose of automatic quantitative and accurate addition of diluent.

detailed description

Please refer to Fig. 1 to Fig. 3, a kind of diluent automatic quantitative accurate addition device 1, comprises a container barrel 11, lower cover plate 13, an upper cover plate 15, four pull rods 17, a feed pipe ball valve 19, a funnel 21. An air inlet pipe joint 23, an air inlet pipe 25, an exhaust pipe ball valve 27, an electromagnetic valve 29, a liquid guide pipe 31, a liquid outlet pipe 33, two observation pipe joints 35, and a liquid level observation pipe 37 .

The lower cover 13 and the upper cover 15 are mounted on the bottom and the top of the container barrel 11 respectively, and the four pull rods 17 are installed on the four corners of the lower cover 13 and the upper cover 15, and are fitted with sealing rings (not shown in the figure), so that the lower cover 13, container barrel 11, and upper cover 15 are installed and fixed into an airtight container.

The feeding pipeline ball valve 19 is installed on the upper cover plate 15 .

The funnel 21 is installed on the top of the feeding pipeline ball valve 19 .

The intake pipe connector 23 is installed on the upper cover plate 15 .

One end of the air inlet pipe 25 is connected to the air inlet pipe joint 23 , and the other end is connected to a constant pressure air source pipeline (not shown), so that the container barrel 11 maintains a constant air pressure. When the gas source pressure is unstable, a pressure stabilizing valve (not shown) can be installed on the intake pipe 25, and the gas pressure can generally be kept between 0.15MPa-0.2MPa.

A pipeline throttling valve (not shown) is installed on the intake pipe 25 .

The exhaust pipe ball valve 27 is installed on the upper cover plate 15 .

The solenoid valve 29 is installed on the upper cover plate 15 .

One end of the catheter 31 is connected to the solenoid valve 29, and the other end extends into the container barrel 11 near the bottom.
